. p METAL WINDOW.

Application filed October 22, 1927. Serial No. 227,968.

This invention relates to ywindows and more particularl to metal windows.`

One of' the objects of this invention is to provide a metal` window construction, in

which a weatherstrip adapted to seal thev nevvable.

, Another object is .to 4provide a simple construction, whichwill be economical to manu facture andeasy to install,

Further objects will appear from the following description, taken in connection with `the accompanying drawing, in which g Figure 1 .isa detail, in vertical section, of

a window embodying this invention; and

' their up and downv movement,

Figure 2 is a horizontal section on line 2f2 of Figure 1.`

Referring to the drawing, 1 designates a window jamb, which may be constructed of sheet metal or other.suitablematerial, in box section, as shown in Figure 2, so as to provide a housing for the sash weights 2. Mounted on the innerV face of the jamb 1 is an auxiliary jamb 3. This auxiliary jamb is preferably constructed with an outstand ing central portion connectedby angular flanges 4 to side flanges 5, which in turn ter-4 minate in lateral flanges 6 engaging theinner face of the jamb 1 and secured thereto by means of screws 7 or other suitable fastenings. Mounted on the jainbl areoutside andinside plat-es 8 and 9, respectively, se-

cured to the jainb 1, byV means of screws 10, rivets 11, or other suitable fastenings. The plates 8 and 9 provide outer and inner guiding flanges 12 and 13, respectively, adapted to guide the upper and lower sash 14 and 15.

Mounted on the auxiliary jamb 3, by means of rivets 16 or other suitableV fastens ings, is a parting stile 17. The stile/17 may be constructed of sheet metal bent back upon itself so as to form guiding flanges 18 adapted to engageV the guide flanges 19 of the sash 14 and 15 to guide the latter in After the bends forming the flanges 18, the metal is bent back to provide flanges 20. The flanges 2O are spaced from the walls of theauxiliary jamb 3 so as to permit the insertion therebetween `of the flange 21 of a strip 22 of resilient material, preferably sheet metal. 'v l The strip 22 is bent outwardly for a poi'- tion ofits width so as to lie againstthe flange 4 of the auxiliary jamb and is then looped back so as to provide a resilient flange 23 adapted to bear against the edge of the flange 19, as shown in Figure 2; This strip, therefore, not only provides a weather seal to keep drafts from passing around the flange 19 from` the outside to the inside of the window, but also bears yieldingly against the edge of the sash so as to keep the same centered and to press the same yieldingly against the guiding flanges of the jamb.

This keeps the sash at all times firmly pressed against its guiding'flangeso `as to keep vit from rattling.

The strip 22 may be applied to the part' ing stile by inserting the flange 21 between the flange 20 and theauxiliary jamb, the insertion being made from the end ofthe jamb.V .Suitable stops 24, secured tothe auxiliary jamb or the flange 420, may be placed at proper points therealong so as to preventthe insertion-'of the'strip1 22 too far and in order to properly position the same. The strip 22 thus inserted is interlocked with the parting stile so as to be permanently held in assembled relation thereto andv in a position to properly engage the flange 19 of the'sash.

It Will be seen, therefore, that this invention provides a window construction which is not only cheap to manufacture, but which isfvery effective in service. The auxiliary jamb 3 has spaced bearing points against the janib l at the flanges 6. ThisY jamb may be adjusted relatively to the sash by mea-ns of the bolt 25, of which there may be any number. l/V ith the auxiliary jamb adjusted to give the proper clearance between the guide flanges, the'strip 22 keeps the sash under a. yielding tension so as to prevent rattling and at the saine time provides an effectiveV weatherfseal. in a location where it is protectedfrom the weather and where it is not subject to cons tact byanyone handling the window. Once in place, therefore, it will be undisturbed throughout its life. In case of wearing out ofthis strip, it is easily replaced by vdis- Inounting the auxiliary jamb and simply inserting a new strip. The `cost Vof repairs nio This strip is placed` Y is thus reduced to a minimum. The parting stile itself is also easily removable in case of excessive wear.

It is obvious that various changes may be made, within the scope of the appended claims, in the details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not limited to the specifie details shown and described.

Having thus described the invention, what is claimed is:

l. In a metal window having a sash, a jamb and a parting stile therealong, a loose strip of resilient material interlocked with the stile and pressing yieldingly against the edge of the sash.

2. In a metal window having a sash, a jamb and a parting stile therealong, a continuous strip of resilient material extending along the stile and pressing yieldingly against the edge of the sash.

3. In a metal window having a sash, a janib and a parting stile therealong, a loose strip of resilient material extending along and intel-locked with the stile and pressing yieldingly against the edge of the sash.

sf. In a metal window having a sash provided with a guide fiange and a parting stile engaging said flange, a continuous strip ol, resilientmaterial extending along the stile and pressing yieldingly against the edge of said flange.

5. In a metal window having a janib and a sash having a guide tiange, an auxiliary janib, a parting stile on said auxiliary jaml), and a resilient strip confined between said auxiliary jamb and said stile and bearing against the edge of the guide flange.

G. In a metal window having a sash, an auxiliary janib, a parting stile formed of sheet metal bent back upon itself to provide a guiding flange for the sash and having a fiange spaced from said jamb, and a strip of resilient material interlocked with said flange and bearing against the edge of the sash.

7. In a metal window having a sash, an auxiliary jamb, a parting stile formed of sheet metal bent back upon itself to provide a guiding fiange for the sash and having a flange spaced from said janib, and a strip of resilient. material confined between said latter flange and said jamb and bearing against the edge of the sash.

8. In a metal window having a sash, an auxiliary jan'ib, a parting stile mounted thereon and having a flange spaced therefrom, and a strip of resilient. material insertahle between said flange and said jaln so as to bear against the edge of the sash.

9. In a metal window having a sash, an adjustable auxiliary jamb, a parting stilo thereon having a guiding flange, adapted to engage the sash, and a loose strip of resilient material interloeked with said stile and pressing yieldingly against the edge of said sash.

10. In a metal window having a sash, an adjustable auxiliary jamb, a parting stile thereon having a guiding flange adapted to engage the sash, and a loose strip of resilient material confined between said auxiliary jainb and said stile and pressing yieldingly against the edge of said sash.

In testimony whereof I aflix my signature this 15th day of October, 1927.
